EtherNet/IP Network Connections
Feed the EtherNet/IP network cable through the
indicator cord grip. Allow enough cable for routing
along inside of enclosure to connector on the
EtherNet/IP module. Connect network cables to
connector on the EtherNet/IP module (see Figure 2-3),
then use cable ties to secure network cables to the
cable tie mounts.

LED Status Indicators
An LED array on the EtherNet/IP module provides
s t a t u s i n f o r m a t i o n f o r t r o u b l e s h o o t i n g ( s e e
Figure 2-6):
• LED 1 provides status about the link
• LED 2 provides status information about the
EtherNet/IP module
• LED 3 provides network status
• LED 4 can be configured to indicate whenever a
packet is sent or received
The LED array can be configured using the Anybus
IPConfig software (
LED configuration 1
,
2
,
or
3
) to
provide different status information, as described
below.
